Low Cost Optimized Diesel Particulate Filter for Low-Temperature Regeneration Developed by NxtGen and Sud-Chemie Results in Savings of up to 40 Percent

    VANCOUVER, May 7 /CNW/ -- NxtGen Emission Controls Inc. and Sud-Chemie
today announced a lower cost, high-efficiency diesel particulate filter (DPF)
optimized for low-temperature regeneration that is attainable by using the
proprietary technologies of both companies. The collaborative development
effort generated up to 40 percent savings as a result of optimizing the filter
with up to 60 percent less precious metal. The announcement was made by Jeremy
Holt, president and chief executive officer of NxtGen and Martin Morrill,
general manager of Sud-Chemie.

    With growing concern over health issues caused by diesel exhaust and
regulations on diesel engines, there has been substantial demand for
cost-effective, advanced diesel exhaust aftertreatment technology that can
operate under a wide range of conditions. In urban environments, many
applications require aftertreatment systems. The systems function under
lightly loaded vehicle conditions at low-exhaust temperatures, which have
lower regeneration temperatures than passive systems and hydrocarbon dosing

    According to Holt, preliminary results indicate the NxtGen syngas
generator and proprietary control algorithm, coupled with Sud-Chemie's
proprietary particulate filter technology, offers a potential solution that is
functional even during low-temperature operation of the engine, including idle

    "Sud-Chemie's technology resulted in a diesel particulate filter that
utilizes up to 60 percent less precious metal than a standard filter and is
more efficient during regeneration and across a broader range of engine
exhaust conditions and temperatures. Depending on the current cost of precious
metals, a savings of several hundred dollars per filter can be achieved,"
Morrill said.

    Together with Sud-Chemie's proprietary wash coat and catalyst technology,
the NxtGen syngas technology provides an opportunity to further develop and
apply diesel engine emissions controls on urban vehicles, which operate at
low-exhaust temperatures.

    The Sud-Chemie Group is headquartered in Munich, Germany. The Sud-Chemie
Needham, Mass. facility contains a fully outfitted engine catalyst facility,
research and development, manufacturing, analysis labs, warehouse, as well as
sales and administrative functions. From the Boston-area facility, the company
provides a rapid response to technical and production needs.

    Sud-Chemie Needham manufactures catalyzed DPF and diesel oxidation
catalysts, as well as three-way catalysts and oxidation catalysts for natural
gas engines and gas turbines. These catalysts are used for reducing the
exhaust emissions from engine-powered generator sets, gas compressors, and
construction, agricultural and mobile equipment.

    NxtGen's syngas technology addresses the emissions challenges of diesel
engines through aftertreatment, but also has applications in combustion
enhancement and for other fuels addressing emissions and CO(2) regulations or
targets. Syngas creation has been successfully scaled for use in light- to
heavy-duty vehicles and upcoming product applications include an active syngas
DPF system for urban trucks that solves particulate filter regeneration
problems caused by low temperature, stop / start city driving and syngas lean
NO(*) trap for NO(*) control to avoid the cost and complexity of urea selective
catalytic reduction systems.

    NxtGen Emission Controls Inc. (www.nxtgen.com) is privately held by
international institutional investors. The company's headquarters and
technology center is located in Burnaby, British Columbia and the
manufacturing and application engineering center is located in Wixom, Mich.
